Description of the offered equipment & services

The proposed equipment will be installed, tested and commissioned by seller.
All equipment is designed for power applications (COP; acc. ISO 8528-1)( latest edition!)
 

. intended for island operation. The operation mode parallel or in island mode will be automatic or manual, depending on as the situation might require.
. The operation of each generating set is carried out from the containerised control room
. The operation method is automatic, with automatic synchronizing, based on a PLC based control system. This PLC will be placed in the control container. The screen will be a 17”

. The proposed equipment includes control equipment, and field instrumentation needed for the operator to monitor the equipment and processes, to give alarm in case of abnormal conditions and to stop the generator operation in case hazardous conditions occur.
. The generator control cubicle will be placed next to the generator set.
. The other controls as foreseen will be placed in the control room.

The generator sets are designed for using h.f.o. (heavy fuel oil) and / or m.d.o. / l.f.o. gas oil (light
fuel oil) (a distillate). If  h.f.o. mode operations is foreseen, the 12CM32C will be able to be started on h.f.o. if sufficiently preheated.

The engineering of the equipment is according to the Caterpillar International Power Systems (CIPS) publication “ Basic Engineering Guidelines And Documentation For Stationary Diesel Power Plants"


The fuels supply, both h.f.o. and l.f.o. will be via a pipeline system which will be build between the tank yard and the power plant.
Anticipated is that the tank yard will only contain the HFO storage tank, the LFO storage tank, the settling tanks, the day tanks and the fuel transfer pump system.
A fuel quantity counter will as well be installed by seller. The pipe line shall have a tap in order to take samples during the transfer of fuel from the storage tank to the plant day tank.
The engine cooling water system will be radiators. To be installed in front of the new power plant building for the CM sets.

Quality control

Quality control, test and inspection procedures applying approved Caterpillar Quality Procedures, are designed to ensure product quality throughout the design, the manufacturingprocess, the construction and the commissioning of the plant.
Each with all auxiliary equipment according to the attached technical specifications.
The total gross site output of the set is according to the relevant ISO & IACS conditions.
The outputs as mentioned are guaranteed until a ambient temperature of 40ºC as might occur at site.
The sets have to be de-rated in output when the ambient temperature is expected to be over 40ºC at site. De-rating is ± 1% of output for every 2ºC increase.

Main advantage of Caterpillar equipment,
 

- fuel consumption

The generator sets as offered, 12CM32C, have a guaranteed low fuel consumption.
The fuel consumption measured at the shaft of the engine is guaranteed under ISO conditions at 179 grams per kWb incl. the engine driven lubricating oil pump.

The Specific Fuel Oil Consumption at Kotu site for the 12CM32 sets under site average ambient circumstances, based on output at the generator terminals, the fuel consumption will be as follows:

Load Factor Fuel Consumption Tolerance

. 100 % load 188 g/kWh 5%
. 80 % load 188 g/kWh 5%
. 75 % load 189 g/kWh 5%
. 50 % load 197 g/kWh 5%

The guaranteed fuel consumption for the generator set as offered is for all fuels with a lower fuel specific heat value (LCV) of 42 700 kJ/kg as described in ISO 3046/1, latest edition, as well as the standard ISO reference conditions.
The average ambient temperature at site shall not exceed 40ºC for these calculations.
During measurement at site, the actual fuel consumption will be re-calculated towards ISO conditions with taking the actual used fuel LCV into consideration.
If ambient conditions at the Site during performance tests at site are different than site reference conditions mentioned above, ISO 3046 standard shall be used when measured values are compared to Guaranteed Performance given in this Contract. Performance tests at Site shall be made in accordance with the Performance test procedures as described in the Technical Specification.
If we take into consideration, the ISO 3046 standards, the ambient conditions at site and the generator efficiency as guaranteed,

Seller is able to guarantee a fuel consumption of 200 grams per kWe at generator terminals at a load of 80 to 100% MCR. This without any tolerance!
(MCR is maximum continuous rating)

-lubricating oil consumption

The generator sets, 12CM32C have a guaranteed low lube oil consumption.
The expected lubricating oil consumption is 0.6 gram per bkWh.
The guaranteed Specific Lubricating Oil Consumption shall be nor more as 3.5 litres/hour per engine and this shall be measured during operation at a load as described it the Performance test Procedures during 48 hours. This SLOC test shall be held during a period between the first 500 to 1000 running hours of the engine.

If the guaranteed lubricating oil consumption cannot be met necessary repairs and adjustments shall be made.

Installation period,

Ten (10) months after purchase order issue. excluding force majeure.
All equipment will be turn-key installed at the new plant as described in the separate technical specification. The delivery date is the date of the signing of the Final Taking Over Certificate.
The installation period will be extended with any delays beyond our control.
The installation period at site will be 24 weeks after the arrival of the equipment at site.

Guarantee

The guarantee period for all equipment is twelve (12) months from start-up, however, not more than eighteen (18) months from the date the equipment is ready for delivery.
The warranty period begins either on the date of taking-over or upon the date when the equipment was taken into commercial use, whichever first occurs. The warranty period ends twelve (12) months thereafter or after eighteen (18) months after the date of delivery (ex works) of the equipment, whichever first occurs.”

Arbitration,

Any differences, disputes or controversy arising between Parties shall be settled within a period of four (4) weeks after the talks on the subject broke down in accordance with the rules of the Chamber of commerce in Paris, France, the decision of this arbitration committee will be accepted by buyer and seller.

Description of the equipment as offered,
